Torrllwhom it mag concern: p

. Be itknown that I, Mourns C. HARms, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvement in Chase Racks for Printers, of which the followingis a 'specification. j i The objects of the. present invention are toprovide a chase rack. that willacoommodate'different widths andlengths of chases with equal facility Without adjustment of any kind. 1 Y i To provide a chase rack that will accommodate the maximum number of chases with a minimum floor space without unduly increasing its height, and in which. forms can be easily and quickly placed in and with drawn from said rack without danger or possibility of injuring or marring the next adjacent forms rubbing or scraping.

To provide a chase rack simple in construction that will satisfactorily and economically take care of live and dead forms and at the same time provide stone room for live or dead type or galleys on top of said rack. i 1

Further objects and advantages will appear from the. following description, it being understood that various forms, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings:

My self adjusting chase rack, the sub ject matterof the present invention, consistsof a substantialand rigid framework 10 ofthe required dimensions, having two ofits opposed sides at right angles with a the top and bottom thereof and one or both offlits othertwo sides orends slanting or pitching downward and outward at an angle, as shownat 10 inF-igure 1. The top 11, is. flat and is torn or floor 12 extends runways 14:, at a floor, threaded orpivoted on. a rod 16 of 90 sidesjof the shoe, 17 are away along, its middle part. This nausea 105 1920.

of the proper lengthwise framework,

Strips of hardwood 1313 size are securely attached to. the floor or bottom of the a properydistance apart to permit a chase 9 being easily inserted between ad acent strips. .Alternatestrips 13 areset flush or nearly-flush with the end of the framework; intermediate strips 13 having rounded orlpointed ends, are uniformly set back a distance from the front of the frame- 7 5 work, andparallel with adjacent strips 13 as shown in Figure 3. This causes the compartments or runsll to recess back from the front of the rack in pairs, with the exterior dividing ways 14 extending forward to the front of the rack. This causes a wide opening in front of each pair of runs, and permits a chase 9 to be easily inserted in the runways 14. Rotatable rollers 15 countersunkin the runways 1 1 aid in handling large chases andheavy forms. i I

Immediately over and in line with the proper height from the proper size, attached to the framework 10, at the sides of the rack, is a series or plurality, of shoes or guides 17-:1'? adapted to receive and'liiolda chase, 9 in avertical posi .tion in the rack 10. The shoes orguides 17*17? consists ofa rectangular piece of metal rabbeted out to permit the end or side ofa standard chase to be, comfortably inserted the rabbet 8. For a little distance, at the bottom or shoe 17 the rabbet 8 isywidened out, causing theshoe .17,to be wider at the bottom or lower end than "atits other part. i The outer chamfered or cut the upperand lower portion or ends of the shoe-17 to be wider than its middle part, and also causestheflange of theshoe to be of uniform thickness, except at the top on upper end of the shoe, where the flange :is 110 and may be utilized 0 guide-strip 13 of adjacentrun- 80 lower end of the left wide and heavy. At the top or upper end of the shoe 17 about the center of its wide part, a round. opening or hole 22 is made cr0sswise of the shoe in both flanges, so that it may be pivoted or suspended on a rod or axis 16. The back of the shoe 17- -17 at its lower end, is slightly cut away, forming downward projecting lugs 19. Slight projections or lugs 20 extend outward from the flange at the widened or flaaed part of the shoe at its lower or free en The shoes orv guides 1717 are of two lengths and are alternately suspended or pivoted on a rod or axis 16 passing through openings or holes 22 in the upper end of the shoe. This brings the bottom of the shoes a distance below the rod or axis on which they are pivoted, and adapts them to care for different widths chases. A plus rality of apertures 18 are provided in spaced relation in the frame 10 for engaging the ends of rods 16 whereby said rods 16 may be secured at different levels, as described.

The rabbeted side 8 of the shoe 17-47 is faced outward, and suitable washers hold the shoes a distance apart. The wide end of the long shoe 17 extends below the wide end of the short shoe 17. This gives room for clearance and eliminates any danger of a shoe 17 coming in contact with and raising its adjacent members when a chase 9 is being inserted in the run 10. The wide part at the bottom of the shoe 17 permits the end or side of a'chase 9 being easily inserted in the shoe. The projecting lugs 19--2O increases the depth of the shoe 1717- and gives the shoe a better hold or grip on the chase 9. The thick flanges at the upper end of the shoe 1'? gives the shoe a good bearing surface on the rod or axis 16 on which it is pivoted or suspended. The guides or shoes 17-17 may be raised or lowered in the rack by moving the rod or axis 16 on which they are suspended to corresponding openings 18 in the frame-work 10*.

In practice, the lower edge of a chase 9 is placed between extending strips 13 forming the outer guides of adjacent pairs of runs 14:; the chase 9 is then shunted or moved against oneof the projecting strips 13, which causes it to rest or lay directly in front of and in line with the run or compartment 14 in which it is to be placed, and also in line with one of the shoes or guides 17-17 suspended above it fromt'he rod 16. The chase 9 is then moved backward between adjacent strips 13 v and13 and entered in the corresponding shoe'or "guide 1717. The chase 9 is then raised' to a horizontal position and moved backward in the run 14-. The pressure of the chase 9'against the shoe 17 causes the shoe 7 to swing upward and backward on the rod 16 and ride on the top edge of the chase The chase 9 is then pushed bacl' ard in the run until the outer end clears the rounded or pointed end of intermediate strips 13". This permits a second chase 9 to be similarly entered in the companion run 14. The shoe 17 and its projecting lugs l920 hold the chase in a vertical position in the rack.

The downward and outward pitch or slant of the ends of the chase rack permits the chase 9 to be handily reached at the top or upper side, even though the bottom or lower side is out of sight. This construction also permits the floor 12 of the rack 10 to be extended out beyond the line of the suspended shoes 17-17 and permits the lower or bottom side of the chase 9 to be entered or fitted in the run 1 1 before the top side is in position to enter the shoe or guide 17-17. A further object sought in making the ends of my chase rack with a downward and outward pitch or slant is: if it is desired to add a second story or tier for additional chases it can be done on the same general. plan as the first or lower tier of runs, as shown at 12 in Figure 1.
